table lock

Hi all,

how can check which table(s) is being locked. I remember v$lock and another v$ join together will do it but I am blank now....

set showmode off echo off
set heading off pagesize 0 linesize 80 timing off feedback off
set termout off verify off
rem
rem Script: userlocks.sql
rem Purpose: List locks on tables and other objects currently held
rem by user sessions, including session information and commands
rem to kill those sessions.

set heading on pagesize 60 termout on
select username,v$session.sid,serial#,owner,object_id,object_name,
object_type,v$lock.type
from dba_objects,v$lock,v$session where object_id = v$lock.id1
and v$lock.sid = v$session.sid and owner != 'SYS';
set heading off pagesize 0
!echo
!echo To kill locking sessions:
select 'alter system kill session ''' || v$session.sid || ',' ||
serial# || ''';'
from dba_objects,v$lock,v$session where object_id = v$lock.id1
and v$lock.sid = v$session.sid and owner != 'SYS';
!echo
set linesize 80 termout on heading on pagesize 24 timing on feedback 6
set termout on verify on echo on showmode both

How long does it take to exec the script you gave to me.

it has been running for 10 mins. normal?

Try running the first part.

select username,v$session.sid,serial#,owner,object_id,object_name,
object_type,v$lock.type
from dba_objects,v$lock,v$session where object_id = v$lock.id1
and v$lock.sid = v$session.sid and owner != 'SYS';
